Taking a Car Seat on Holiday: The Complete UK Guide (2026)
By BabyTravel UK Editorial Team · Last updated July 2026
Whether you fly, sail, or drive, here is what to know about getting your baby's car seat there safely, and when to leave it at home.
The car seat question causes more pre-holiday stress than almost anything else, and it is easy to see why. It is bulky, it is expensive, and the rules seem to change depending on who you ask. The short version is reassuring: you can take a car seat on a plane, most airlines carry it for free, and for a hire car abroad you can usually bring your own or rent one. Which you choose depends on the trip. Here is how to decide, and how to get the seat there in one piece.
Quick Answer
Yes, you can take a car seat on a plane. Most airlines let you gate-check it for free alongside the pushchair. For a rental car abroad you can either bring your own seat or rent one, but rental seats are often tired and poorly fitted, so many parents bring their own. Whatever you decide, a padded travel bag protects the seat in transit, and you should always check the car seat laws for your destination before you travel.
Car Seat on a Plane
Most UK airlines treat a car seat as an essential item for an infant and carry it free of charge, one per child, on top of your normal baggage. In practice you have two options. You can gate-check it, wheeling it to the aircraft door and collecting it there or at the carousel, which is what most families do. Or, if you have bought a seat for your baby, you can take an aircraft-approved car seat on board and strap it into the plane seat, which is the safest option for the flight itself but only worth it if you are not travelling with a lap infant.
The catch with gate-checking is handling. Car seats go into the hold with everything else, and they can come back grubby or, occasionally, damaged. A padded car seat travel bag is cheap insurance, and it gives you something to carry the seat in through a busy terminal. Our guide to your baby's first flight covers the wider airport routine, and each of our flying with a baby airline guides lists that carrier's exact policy.
Car Seat in a Rental Car Abroad
When you land, you have a choice: fit your own seat into the hire car, or add a rental seat to the booking. Bringing your own is often the better call. You know it is clean, you know it is not been in a crash, and you know how to fit it. Rental car seats are a lottery. They are frequently older models, sometimes missing the manual, and the desk staff rarely have time to help you fit one correctly in a hot car park with a tired baby in your arms.
If you do bring your own, check two things first. Confirm your seat's fitting method matches the hire car: most European hire cars have ISOFIX points, but not all, and a belt-fitted seat needs a compatible seatbelt layout. And build in time to fit it properly on arrival rather than rushing it at the kerb. If you would rather rent, book the seat in advance, ask for the specific model, and inspect it before you drive off.

Every popular European holiday destination requires young children to travel in an appropriate car seat or restraint, but the exact thresholds for height, age, and front-seat use vary from one country to the next. Broadly, across the EU a child under 135cm tall generally needs a suitable car seat or booster, but do not treat that as gospel for any single country. Rules change, and the fine for getting it wrong is the least of your worries.
| Country | General rule for young children |
|---|---|
| UK | Car seat required until 135cm tall or age 12, whichever comes first. |
| Spain | Appropriate restraint required for children under 135cm; under-135cm generally not allowed in the front. |
| France | Car seat or booster required up to age 10 or an appropriate height. |
| Portugal | Restraint required for children under 135cm; under-3s must use a proper seat. |
| Italy | Car seat required under 150cm; anti-abandonment alarm required for under-4s. |
| Greece | Appropriate restraint required for young children; check current front-seat rules. |
Treat the table as a starting point, not the final word. Always confirm the current rules on the UK government's foreign travel advice pages for your destination before you go, especially the front-seat and anti-abandonment rules, which catch a lot of families out.

Car Seat on a Ferry
On a ferry your baby does not need to sit in the car seat during the crossing. Once you have parked on the car deck, everyone heads up to the passenger decks and you carry your baby or use a sling or pushchair as normal. The car seat stays in the car. The only time it matters is loading and unloading, when your child rides the short distance on and off the ship in their seat as usual.
Car Seat on a Train
You do not need a car seat on a train, and you would not have anywhere to fit one. That said, some parents bring a lightweight seat or travel booster on longer journeys purely to contain a wriggly toddler in a reserved seat, or because they are picking up a hire car at the other end. For most train trips, though, it is one less thing to carry. Our guide to travelling on UK trains with a baby has the rest.
Alternatives to Bringing Your Own
If lugging a car seat through an airport fills you with dread, you have options. You can rent one with the hire car, though quality varies, so book the model in advance and inspect it. Some destinations have specialist baby-equipment hire firms that deliver a good-quality, well-maintained seat to your accommodation, which is often better than the rental desk. A compact travel car seat, lighter and slimmer than your everyday one, is worth considering if you fly often. And in cities where you will mostly use taxis, some booking apps let you request a vehicle with a child seat fitted.
Protecting Your Car Seat in Transit
If you are taking your own seat, protect it. A padded travel bag keeps it clean and cushions it against the knocks of hold handling, and the same few in-car extras below make the drive at the other end calmer for your baby.

Frequently Asked Questions
Can I take a car seat on a plane UK?
Yes. UK airlines treat a car seat as an essential infant item and carry it free of charge, one per child, on top of your baggage allowance. You can gate-check it to the aircraft door, or, if you have bought a seat for your baby, take an aircraft-approved car seat on board and fit it to the plane seat.
Do airlines charge for car seats?
Most do not. The large majority of UK and European airlines carry an infant car seat and a pushchair free of charge. Policies do vary, though, so check your specific airline before you fly. Our individual airline guides list each carrier's baggage rules for baby equipment.
Should I take my own car seat abroad or rent one?
Bringing your own is usually the safer bet. You know its history, you know it is clean, and you know how to fit it. Rental seats are often older models with no manual and little help fitting them. If you would rather rent, book the specific model in advance and inspect it before you drive off.
Can I use a UK car seat in Europe?
Generally yes. A car seat that meets UK and European safety standards (the same ECE regulations apply across the EU) is legal to use in most European countries. Check that the fitting method suits the hire car, since not every car has ISOFIX, and confirm the destination's height, age, and front-seat rules before you travel.
How do I protect my car seat on a flight?
Use a padded car seat travel bag. It keeps the seat clean, cushions it against knocks in the hold, and gives you a way to carry it through the terminal. If you are checking it into the hold rather than gate-checking, padding matters even more, as it faces rougher handling.
The Bottom Line
For most trips, bringing your own car seat is the calmer choice: you trust the fit, you trust the condition, and you protect it with a cheap travel bag. Rent only when you have checked the model and the terms. Above all, look up the car seat law for your destination before you fly, because that is the detail that trips families up.
